Warming Disrupts Plant-Fungal Endophyte Symbiosis More Severely in Leaves Than Roots.

Disruptions to functionally important symbionts with global change will negatively impact plant fitness, with broader consequences for species' abundances, distribution, and community composition. Fungal endophytes that live inside plant leaves and roots could potentially mitigate plant heat stress from global warming. Conversely, disruptions of these symbioses could exacerbate the negative impacts of warming.

Canopy complexity drives positive effects of tree diversity on productivity in two tree diversity experiments.

Forest canopy complexity (i.e., the three-dimensional structure of the canopy) is often associated with increased species diversity as well as high primary productivity across natural forests.

Soil microbial community response to ectomycorrhizal dominance in diverse neotropical montane forests.

Ectomycorrhizal (EM) associations can promote the dominance of tree species in otherwise diverse tropical forests. These EM associations between trees and their fungal mutualists have important consequences for soil organic matter cycling, yet the influence of these EM-associated effects on surrounding microbial communities is not well known, particularly in neotropical forests. We examined fungal and prokaryotic community composition in surface soil samples from mixed arbuscular mycorrhizal (AM) and ectomycorrhizal (EM) stands as well as stands dominated by EM-associated Oreomunnea mexicana (Juglandaceae) in four watersheds differing in soil fertility in the Fortuna Forest Reserve, Panama.

Clinical presentations of erosive esophagitis found at endoscopy in neurologically impaired children: a historical study.

Background: Data is lacking as to the clinical presentation of erosive esophagitis (EE) in neurologically impaired children compared to non-neurologically impaired children (non-NIC). To determinate the clinical presentation, associations, management, and outcomes of EE in neurologically impaired children compared to children without neurologic impairment.

Methods: Retrospective chart review of all esophagogastroduodenoscopies performed in pediatric patients at the University of Mississippi Medical Center from 1998 to 2020 with the diagnosis of EE.

Evaluating the regulation of transporter proteins and P-glycoprotein in rats with cholestasis and its implication for digoxin clearance.

Background: Cardiac and hepatic functionality are intertwined in a multifaceted relationship. Pathologic processes involving one may affect the other through a variety of mechanisms, including hemodynamic and membrane transport effects.

Aim: To better understand the effect of extrahepatic cholestasis on regulations of membrane transporters involving digoxin and its implication for digoxin clearance.
